| 제목 | Adsorption properties of mono-dispersed DDR zeolite particles for CO2, N2, and H2O |
| 초록 | Si-DDR zeolites have proper pore size to separateCO2 from N2 based on the size difference. Even though Si-DDR zeolites have potentialas CO2 separator, synthetic method using mono-dispersed DDR zeolites have not beenwidely used. We present the synthesis method of mono-dispersed Si-DDR which havediamond shape by using seeded growth of irregular Si-DDR particles. In Si-DDR particles,the adsorption isotherms and heat of adsorption of CO2, N2, and H2O were goodenough to compare with the literature. At 303 K, CO2/N2 ideal sorption weremeasured ~15.3-18.0 and permeation selectivities were measured ~7.7-9.0. Theseresult means that all silica DDR zeolites are active as a membrane for CO2/N2separations. Furthermore, the presence of H2O affects the quantity of defectsin Si-DDR framework. |
